Title: Improvements relating to electric arc converters
IPC: H01T11/00
Filed: 1937-03-18
Abstract: 497,479. Converting. MARX, E. March 18, 1937, No. 7985. Convention date,March 18, 1936. [Class 38 (ii)] [Also in Group XL] In an electric arc converter in which the arc L burns in a current of gas between two main electrodes A, B, an auxiliary arc current is introduced into the main arc for control purposes by one or more auxiliary electrodes E adjacent the main arc so that the additional arc current is supplied to the main arc at a point or points between the main electrodes, so as to change the value of the current flowing in part of the main arc. The auxiliary electrodes E may be of ring form surrounding the normal arc path. If the auxiliary arc current is in the same direction as the main arc, the voltage drop across the main arc is reduced. The auxiliary arc current may be varied periodically. A reverse arc is obtained by applying an impulsive negative voltage between the auxiliary electrode and the cathode B as by means of a charged condenser whereby the main arc voltage is raised. If the reverse arc current is equal to the main arc current, the latter is extinguished. The reverse arc current may be started periodically. Any known means for starting the main arc may be used. The invention may be applied to rectifiers, inverters or frequency changers. The Specification as open to inspection under Sect. 91 referred to the application of the invention to the extinguishing of arcs used as switches. This subject-matter does not appear in the Specification as accepted.

They are also preferably used in the "equilibrated state", i.e. in a state when the distribution of the different structural units in the polysiloxane skeleton and also the M.W. distribution of the polymeric mixture are almost in conformation with the statistical equilibrium.  Their viscosity should also preferably not exceed 1000 cP at normal room tenperature.  Their distribution throughout the foaming mixture is preferably non-uniform so as to produce a good sponge-like structure, wherein there are zones of collapsed cells and zones of very fine cell-structure.

Filed: 1919-12-22
Abstract: In a mobile and atomizable fuel which consists of peptizable solid carbonaceous substance suspended in liquid hydrocarbon or fuel oil and which is preferably heavier than water, stability of the suspension is promoted by the addition of 1-10 per cent of a peptizer, such as creosote, naphthalene, anthracene-free oil, or other coal distillates, or tar derived from solvent naphtha.  The carbonaceous substance is pulverized or otherwise reduced until about and preferably more than 95 per cent passes through a screen of 100 mesh to the linear inch and 85 per cent through a screen of 200 mesh, and is then mixed with the liquid hydrocarbon by passage through a ball, tube, or paint mill, or by heating to 65-95 DEG  C. with or without agitation, or by a combination of these methods; or the solid may be reduced in presence of the liquid. Suitable carbonaceous substances specified are semi-anthracite, bituminous and semi-bituminous coals, and lignites.  Suitable liquids mentioned are fuel oils, pressure-still oil or tar, coal tar from coke ovens or gas works, solutions of pitch, and molasses.  The liquid should preferably have a viscosity of about 20 DEG  Engler at 20 DEG  C. and 10 DEG  at 30 DEG  C.  Liquid products may be obtained containing up to 45 per cent of carbonaceous particles, and atomizable pastes containing up to 75 per cent solid particles.  Other measures promoting stability may be used in addition, as described in Specification 149,306.  Specification 17729/13 also is referred to.
